[Suggestion] Chunk Materials

[Ayliroe]

Here's an implementation I found working you can add to your tutorial:

• ChunkBase.h:
  
  (A blueprint-accessible array for materials, plus arrays for the material struct and vertices instead of single values)

• ChunkBase.cpp:
  
  (On clearing, empty the arrays then refresh using the total amount of materials, not blocks)

• NaiveChunk.cpp, in GenerateMesh():
  
  (Get the material for the current block's face, minus 2 to skip null and air enums, clamp as a safety, then pass it to CreateFace() )

• NaiveChunk.cpp, in CreateFace():
  
  (Switch all mesh structs and the vertex int to the new arrays)

• GreedyChunk.cpp, GenerateMesh():
  
  (Same as NaiveChunk, but using CurrentMask.Block for the face's material)

• ApplyMesh():
  
  (First clear all previous sections, then generate a new one for each material on the chunk)

Basically the same code as before, but generates one unique section for each different block material. Straightforward to scale-up (just add materials to the array) and supports both naive/greedy meshing. Maybe you had something in mind too of the like.

I was pondering on the same issue for a while, I was thinking of having 2 Materials (One base martials with texture arrays) and one for fluids like water with some other effects, for a while I as thinking on creating 2 separate meshed that means 2 runs of meshing algorithms which won't be performant, Didn't think of mesh sections. this is a nice scalable solution. I'll be sure to include this and credit you.

Thanks

What is GetID on the third image?

@Ayliroe Hey man. I sadly cannot seem to get your code to work. mind adding me on discord so I can bother you there haha?
No seriously please add me on discord I really need the help here is my username "anasdev"

Code is bad documented and causes out of bounds array. Git is literally a version controll Software that allows you to make branches of diffrent types of versions.
@AnasTheDev Did he help you, or did you get it otherwise?
